Weather widget

Has anyone experimented with things like weather widgets, or something as simple as displaying time and date. Soo many things that were easy on the old CTC's that just aren't straight forward anymore.

Had a search through the documentation but haven't seen anything obvious yet.

 

Thought I would just put this here in case any one else was reading this ...

I used the following to get time to display ..

Object, Create User Parameter in App 250, Address 0, Called "Time"

Scripting, Create new Resident Script with interval 60 seconds.

Script has the code:

hour = os.date('%I')
min = os.date('%M')
ampm = os.date('%p')
SetUserParam(0, 0, hour..':'..min..' '..ampm)
​

Add new object to a visualisation connected to 0/250/0

Feel free to tell me there is a better way

 

Hey there, I assume the rest of your code is something like
hour = os.date('%I', os.time())
etc.

My issue is that I don't appear to be able to update the user parameters.

I created a user param of type Time/Day, and have assigned the value to that param.

I can write the correct value to the log however cannot update the user param.

Any prod to something I may be doing wrong?

Cheers,
Paul

 

Whoops, should have been
hour = os.date('%I', os.time())

 

So I created two user params for time string and date string.

Run a script once a second

Code:

local TimeString = os.date( "%H:%M:%S", Timestamp )
local DateString = os.date( "%A, %d %B %Y", Timestamp )

SetUserParam('Local Network', 'timestr', TimeString)
SetUserParam('Local Network', 'datestr', DateString)

Place them somewhere on your page, and you'll have time and date displayed.

 

Create a free API account on Willy Weather, I believe you can hit it a lot of times before you start getting charges. Check out their API docs for the different functions available.

Create some user params for weather_min, weather_max, weather_icon, weather_precis, precisCode

Upload some icons for sunny, cloudy, etc. Add the user params item to the page somewhere and add a bunch of icons for values 1, 2, 3, 4, etc for the total number of precisCode values. This is trial and error as I haven't found a complete listing of text.

Code:

local http = require("socket.http")
local json = require "json"

--local body, code, headers, status = http.request("https://api.willyweather.com.au/{API_KEY}/locations/1215/weather.json?forecasts=weather&days=1&startDate=2019-04-23")
local body, code, headers, status = http.request("https://api.willyweather.com.au/{API_KEY}/locations/2370/weather.json?forecasts=weather&days=3&startDate=2019-04-23")

log(code, status, body, #body)

local decode = json.decode(body)

--log(decode.location.name)

local entry = decode.forecasts.weather.days[1].entries[1]

log(entry.precis)

-- degrees characters don't work :(
local minimum = string.format("%s %sC", entry.min, string.char(176))
local maximum = string.format("%s %sC", entry.max, string.char(176))
local precisCode = entry.precisCode
local precis = entry.precis

-- Set value of user parameter 'now_temp' on local network to 12.1
SetUserParam('Local Network', 'weather_min', minimum)
SetUserParam('Local Network', 'weather_max', maximum)
SetUserParam('Local Network', 'weather_precis', precis)

if (precisCode == "chance-shower-fine") then
  SetUserParam('Local Network', 'weather_icon', 4)
elseif (precisCode == "fine") then
  SetUserParam('Local Network', 'weather_icon', 1)
elseif (precisCode == "mostly-fine") then
  SetUserParam('Local Network', 'weather_icon', 5)
else
  SetUserParam('Local Network', 'weather_icon', 0)
end

Think that covers it, you should end up with a display like . . .



Call a few more API methods and you can add more cool stuff.

 

OK, I can't get this to work... what am I missing?

I've set up the above as a resident script, delay 1 sec.

I've defined two tags (tag map) under User Parameter (250), 'timestr' and 'datestr'

I've added two objects 0/250/0 and 0/250/1 (timestr and datestr respectively) but the values are 0:00:00 and 00.00.2000

 

have you written out to the log as an easy way of just verifying that the time prints. Check the name of your local network, might just be "Local". The user patrameters should be strings, the result above doesn't look like they are.

 

Thanks, that fixed it.

Is it possible to a run script - for example weather - only when a visualisation page is opened to prevent hitting the API too often?

 

No idea, probably not. Its a whole different interface concept to the CTC's. Run it once every 30 min or so, I mean, how often does the weather need to be updated. The time, you can run every second and update the user value.
